Although there used to be generic versions of Westhroid, these have all been discontinued. Generic versions of thyroid USP are currently available, although there is no way to know if they are really equivalent to Westhroid, since none of these products are approved by the FDA.
Westhroid™ (thyroid USP) is a prescription thyroid medication. It is considered a natural form of thyroid replacement, since it is made from the thyroid glands of pigs. Westhroid is used to treat an underactive thyroid (hypothyroidism), as well as a few other thyroid problems.
Westhroid is made by RLC Labs. Generic versions were once available, but they have all been discontinued.
Many people have been frustrated to find that this medication (as well as other similar products) has been very difficult, if not impossible, to obtain lately. Apparently, there has been a sudden increase in demand for Westhroid, and the company has had difficulty keeping up with this increase.
The manufacturer does not know when this medication will again become consistently available. It is possible that a few strengths may become intermittently available initially, before all strengths return to the market. Until then, discuss your other treatment options with your healthcare provider.
**October 2010 Update** The ½-grain, 1-grain, and 2-grain strengths are once again available. The manufacturer is working to resolve the shortage of the other strengths, and it is expected that other strengths may become available soon. In addition, three new strengths (1½-grain, 4-grain, and 5-grain) are expected to become available in the coming months.
